    Default Can I use 2 Motors for 1 axis without slaving one to the other?

    Hi
    I currently have my X axis using 2 motors and the 2nd motor is connected to A axis on my board and is slaved to X axis.
    Is it possible to connect the 2nd drive to the X axis output and use both motors from the same signal?

    If the system is capable of electronic gearing then it should be possible, I do it all the time with the Galil Motion cards.
    (You can even change the gearing on the fly, if needed!).

    Why do I need electronic gearing??

    Electronic gearing usually refers to using one encoder as a slave off the other at what ever ratio you want, in your case it sounds like 1:1.

    In my 3 axis akz250 bob I use 2 drives and 2 motors with the same signal.

    How can I do it on mine? just unplug the pins from the A axis on the BOB andd plug them in the same pins the motor of X axis is? and disable the A axis from mach3?

    That's what I did but as I said my bob is 3 axis so I don't have an A axis. Using the Y signal axis to drive 2 drives was the only way.

    What BOB do you have?

    My BOB has 5 axis output. But once when I tried to home the machine and for no apparent reason the 2 motors rotated in the opposite direction. So I want to have them on the same output to avoid this happen again in the future.

    Hi Jimskeet,

    I think this may help you! Its a Multi-axis stepper driver from leadshine (Leadshine Technology Co., Ltd.) .

    Thanks.

    Are you sure that your homing parameters were the same for the slave axis
